Another object of the invention is to provide forV adjustability of the propeller and rudder. for adapting the water vehicle `to 10 different conditions.

Another object of the invention is to accomplish the above ,purposeswith a structure lwhich ,will be strong and durable and efhcient though inexpensive to manufacture. t .With the above and other objects in view, vthe invention consists in the water .vehicle as herein claimed and' all equivalents.
